euiran s'rAT PATENT @WKQE- WILLIAM D. FULLER, or SPRINGFIELD, OHIO, asslenoa, BY MESNE ass'reivivrnn'rs, TO ELLIOTT 001VIPANY,'OF PITTSBURGH,PENNSYLVANIA, A conrona'rronor PENN- SYLVANIA.

v TUBE-CLEANER.

Application filed October 30, 1915.

To all whom it may concern Be it known that I, \VILLIAM D. .FFTLLER, acitizen of the United States, residing at Springfield, in the county ofClark and State of Ohio, have invented certain new and usefulImprovements in Tube-Cleaners, of which the following is aspecification, reference being had therein to the accompanying drawings.

My invention relates to tube cleaners and more particularly to rotarytube cleaners The object of my invention is to simplify the constructionby the use of fewer parts so arranged as to increase the number of setsof cutters employed.

A further object is to so combine the parts that they can be easilyassembled and readily taken apart for renewal or repalrs.

With these and other objects in view my invention consists of theconstructions and combinations hereinafter described and set forth inthe claims.

In the accompanying drawings which form a part of this specificationFlgure 1 is a longitudinal section of a tube cleaner embodying myinvention taken on the line 11 of Fig. 2. Fig. 2 is a cross-section onthe line 2-2 of Fig. 1. Fig. 3 is a crosssection on the line 33 of Fig.1 and Flg. a is a longitudinal section on the line 4l4 of Fig. 2.

Like numerals represent the same parts in the several views.

In the drawings-1 represents a body having a front head 2 and a rearhead 3, said heads being formed integrally therewith to give a rigid anddurable construction;

and a rearward extension 4 of the body is screw-threaded as shown toattach the cleaner head to a driving shaft.

The front and rear heads are provided with a plurality of pairs ofoppositely disposed bores 5 and in each of these bores there is pivotedvan arm 6 by a pivot pin Specification of Letters Patent.

Serial No. 58,737.

Rotary cutters 10 are mounted on the bolts between the arms. Said boltsproject beyond the front head, the head being cut away at 11 for thispurpose and rotary cutters 12 are mounted thereon between said head andthe heads 9 of the bolts. A spacing sleeve 13 and washer 14 areshowninterposed between the cutters 12 and the front arms.

The body 1 is rectangular in cross-section and the arms 6 are providedwith tail pieces 6 which contact with the body to limit the outwardswing of the arms and their inward movement is limited by contact withthe front head where it has been cut away at 11.

The head is assembled by first placing the arms in position on therespective heads and the bolts with the front cutters, spacing sleeveand washer thereon are then inserted through the cut away portions ofthe front heads and the openings in the free ends of the front arms andthe cutters 10 are mounted thereon as the bolts pass to the rear arms;and when the bolts are screwthreaded to the rear arms, the cutters 10form the means of holding thearms in their pivoted positions in therespective heads.

It will be noted that the pivot pins are formed integrally with andproject outwardly from the arms and do not extend between the arms, andby reason of this construction sufficient space is afforded to permitthe use of four instead of the usual three sets of arms and cutterswhich greatly increases the cutting capacity of the head.

Having thus described my invention I claim 1. In a tube cleaner, arotary body having front and rear heads integral therewith, a pluralityof pairs of oppositely disposed arms, the arms of each pair being spacedapart and having pivot pins seated in openings in the respective headsand removable from the inner sides of said heads and cutters moimtedbetween each opposing pair of arms, substantially'as described.

' 2. In a tube cleaner, a rotary body having front and rear heads, aplurality of oppositely disposed arms having outwardly extending pivotpins formed integrally therewith pivoted .in and removable from bores inthe respective heads, each pair of affixed my signature in the presenceof tWo arms being spaced apart With a bolt ex- Witnesses.

tendin through an 0 enin in the free end 7 of one hf said arms aridseciired to the other ILLIAM FULLER 5 arm and cutters mounted on saidbolt be- WVitnesses:

tween said arms, substantially as described. OLIVER H. HAUsE,
